 Contextual reasoning
– How to improve application capacity to sense, understand, and
reason about complex and dynamic data and situation?
 Knowledge representations and interaction
techniques
– How to augment cognitive reasoning with perceptual reasoning
through visual representations and interactions?
 Data Representations and transformations
– How to transform data into a representation that is appropriate to
the reasoning task and effectively patch the important content?
 Production, presentation, and dissemination
– How to convey analytical results in meaningful ways to various
audiences?
